DOUBLE-HUNG WINDOW SASH.

Application filed FebruaryA 7, 1927. Serial No. 166,562.

This invention relates to window constructions. g

The object of the invention is to provide double hung window sashes withpivoted glass sashes constructed and arranged to be swung upon thepivots to permit cleaning the outside of a window from the inside of adwelling.

Another object of the invention resides in the provision of a windowglass sash swingingly mounted in a sliding window sash, the sasheshaving grooves adapted to register, into and out of which may slidablymove a combined locking and sealing plate whereby to fasten the swingingsash against swinging movement and to exclude air from the room, andwhereby the combined fastening and air sealing device may be moved topermit swinging movement of the swinging sash.

lVith the above and other objects in view, the invention consists in theconstruction and novel combination and arrangement of parts hereinafterfully described, illustrated in the accompanying drawings and pointedout in the claims hereto appended, it being understood that variouschanges in the form, proportion and minor detailsvof construction,within the scope of the claim, may be.

resorted to without departing from the spirit or sacricing any of theadvantages of the'invention.

In the drawings:

Figure 1 is a front elevation of a window construction embodying awindow frame and upper and lower sliding sashes, in each of which ispivoted a glass'sash.

Fig. 2 is an enlarged detailed longitudinal sectional view.

Fig. 3 is an enlarged detailed cross sectional view.

Fig. 4 is a detail view of the combined locking and air excluding meansfor the swinging sashes.

Referring now lmore particularly to the accompanying drawings, thereference character 5 indicates a window frame in which the upper andlower sashes 6 and 7 are slidably mounted in the usual manner andprovided with the usual sash balances (not shown). Each sliding sash hasa groove 8 9 in the inner faces of its opposite sides for a purposepresently understood.

A glass swinging sash 10 is swingingly mounted in each sliding sash, andat each side each glass sash 10 is provided in its outer face with alongitudinal groove -ll fectedin any suitable manner.

adapted to normally register with the respective grooves 8-9 of therespective sliding sashes 6 and 7. The swinging or pivotal mounting ofthe glass sashes 10`may be et- One way ot accomplishing this is toprovide each glass sash 10 with suitablepivots on opposite sides thereoffor engagement in the channel bearing sockets 13 of the upper and lowersashes 6 and 7.

A suitable device for locking the swinging glass sashes against swingingmovement and to exclude air, is provided, there being a pair of devicesfor this purpose associated with each of the upper and lower windowsashes. In the drawings there is a locking plate 14 adapted normally tocover the joint at each side of each of the upper and lower windows, theplate 14 lying in the respective grooves of the sliding and swingingsashes and being disposed over the joint to lock the swinging sashesagainst movement and eX- clude air at the sides of the sashes. Eachplate 111 has a lateral projection 15 which extends into a recess 16 inthe side of the respective sliding sash, and along its lower edge eachprojection 15 is provided with gear teeth 16a. A pinion 17 is mounted ineach side of each sliding sash on a shaft 18 which has its outer endjournalled in a bracket 19 on the respective sliding sash and projectingthrough the bracket sufiiciently to permit the application of a suitabletool (not shown) for rotating the pinion 17.

By rotating the respective pinions 17 in one direction it will beunderstood that the plates 14 will be withdrawn from the respectivegrooves in the sides of the swinging glass sashes beyond the side jointsbetween the latter and the sliding sashes, so as to permit swingingmovement of the sashes on their pivots 12. `Upon bringing the swingingsashes into closed relation with the sliding sashes, the rotating of thepinions in the opposite directions effects locking of the swingingsashes against swinging movement and also prevents air passing betweenthe sides of the swinging and sliding sashes. The plates 14 are of alength substantially the length of the swinging sashes.

From the foregoing it will be seen that I provide a window constructionwherein the usual sliding sashes carry swinging glass sashes so as topermit the cleaning of the outside of the glass from the inside of thedwelling, and that the swinging glass sashes may be held in lockedposition oy a device which effects not only the lockingbut serves as anairy sealing device at the sides of the a longitudinal groove intheinner face ofv each side, a glass sash pivoted in each sliding sash andveachirprovidedwith alongivtudinal'groove inthe outer face of each sideto align with the respective'grooves of the respective sliding sashes',a plate mounted in the aligning grooves of thel sliding and swinging,slashes at web Sid@ Qf the latter and each plate having an integral,flat lateral projection intermediate its ends eXtendyplates out oftherespective grooves of the swinging glass sashes to permit swingingmovement of the' latter, the'pivotso' the g'ass sashes being spacedfrom' the plates and their projections. i 'A i 1n testimony whereof havehereunto set my' ihand.
